Simulation of power angle controlled voltage source converter using a linear quadratic method in a wind energy application

The design, analysis and simulation of a power angle controlled voltage source inverter in a wind energy application are addressed. By controlling both the phase displacement angle and voltage amplitude, the performance of the conversion system is improved compared with the traditional power angle control. The system becomes a multiple-input and multiple-output system preferably controlled by the linear quadratic method. To reduce harmonics and noise, a Kalman estimator is applied to the input signals of the controller. When state equations are used, the inverter system as well as the feedback and feedforward parameters are easy to handle by using the Matlab/Simulink program. The simulation results show that the proposed control method and its implementation function adequately.
